xv around 2014/2015 originally had gambit system, the datamine confirmed it
one of the names mentioned in the datamine was calling it the Stratagem system so as to not have it called gambit like ff12 but functionality it was the gambit system

it got cut at some point after episode duscae released but remnants of it remained in the form of the party AI behaviour, in particular the ascension menu node unlocks for what the party AI does, like party healing or using medkits on nearby allies or ignis using venomshock or whatever

the original battle system that Tabata patented for ffxv in 2012 had an explicit if>then gambit system functionality too
